To provide a frequency channel estimation data generator 30 capable of reducing a processing load and the like when generating frequency channel estimation data for reproducing frequency distortion of a reception signal.

The frequency channel estimation data generator 30 has: a correlator 31 calculating a correlation value between a reception signal and a preamble signal at a plurality of different delay timings while shifting the preamble signal; a power calculation section 33 calculating the power of the correlation value at each delay timing; a threshold calculation section 34 specifying the maximum value among the calculated power of the correlation values in a time period of one frame, and calculating a predetermined proportion of the specified maximum value as a threshold; a correlation value specifying section 35 specifying the correlation value corresponding to the power equal to or more than the threshold among the calculated power of the correlation values; and a time-frequency conversion section 36 performing time-frequency conversion to the specified correlation value to generate frequency channel estimation data.
